We don't recommended to combine 2 or 3 rings at same time if the focal length is less than 70mm.the auto focus is easy when mount ONE ring , but difficult for 2 or 3 . we suggest to set your camera in MF .
Please see 5th image , that's my testing data , hope that's helpful for your photograph , if you still have any problems for using it , please feel free to contact me , i will support technocial support , thanks
